      Please attach (use Go Advanced) good clear pictures of the whole backside of the TV showing all the boards so we can see what we are dealing with.
      What is the power supply board P/N? BN44-?????

                  Hello Community!

                  CASE DETAILS

                  Promblem Signs: Backlight on 1 sec off 7sec > repeat && Red standby light: 1blink, off 3 sec, 2 blinks, off 5 secs, 2 blinks, off 3 sec, restart cycle

                  13V present on powerboard output. Backlight continues flashing after removing cables to pannel one at a time and even with both disconnected. NOTE: backlight STOPs flashing and remains on when connector between powerboard and mainboard (note Tcon built in) is disconnected.

                  Tried inserting firmware on USB and left it in for a few hours, but no change
